Four in Four - Addition and Subtraction Set A - 4d and 3d

The "Four in Four" exercise from KS2Gems is a timed challenge designed for Year 4 students to test and enhance their addition and subtraction skills. Each worksheet presents four problems, mixing 4-digit and 3-digit numbers, which the children are tasked to complete within a four-minute time frame. The problems are laid out in a clear and straightforward manner, requiring students to perform calculations such as 6004 - 298 and 5643 + 437 on Sheet 1, with subsequent sheets offering a similar variety of numerical challenges. This activity not only helps in reinforcing arithmetic proficiency but also in developing time management skills.

The exercise includes multiple sheets, each with a new set of calculations to keep the students engaged and challenged. For example, Sheet 2 features problems like 6832 + 397 and 8982 - 867, while Sheet 3 presents calculations such as 7872 - 245 and 3832 + 254. The answers are provided separately, allowing for easy marking or self-assessment. For instance, the answer section reveals that 1265 + 172 equals 1,437 and 2857 - 659 equals 2,198, among others. This structured practice is an effective way to build confidence in young learners as they master the fundamental skills of addition and subtraction.
